Letters Patent No. 113,599, dated April 11, 1.871.

IMPROVEMENT IN OIL-RESERVOIRS FOR AXLEBBOXESS The Schedule referred to in these Letters Patent Aand making part of the same.

To all whom tt may concer-n lubricated, and from which the oil is conducted to the journal, by capillary attraction, through a wick or strips or sheets of felt; and consists 'of the combination, with such an open reservoir, of a plate or diaphragm itting closely at the edges, and provided with yacentral ,'opening, through which the Wick is passed, whereby the oil is prevented i'rom slopp'ing or escaping over the upper ledges of the reservoir, the object being to prevent the loss of oil occasioned by the slopping or spilling over, which usually takes place in axle-boxes when my invention is not employed.

In the drawlng- Figure l isa longitudinal section of an oil-reservoir having this improvement.

Figure 2 is a plan of the same.-

Each part is distinguished by the same letter' when ever it appears in the drawing.

To enable others skilled in the art or science to which it most nearly appertains to makel and use my invention, l will proceed to describe fully its construction and operation.

A is a rectangular box, which is placed under the journal to be lubricated, and slides in and out of the axle-box like a drawer. Y

B is a rectangular plate, having legs O.

The box A may be made'a little larger at the top than at the bottom, and the plate B may be made to t the inside ofthe box about half-way down-that is to say, one of the ends or sides may be made inclined.

The legs' C should not quite touch the bottom when the plate Bis in its place.

By constructing the apparatus in this manner the shaking of the axle-box will settle thc plate B down in the box A when the machine is in motion, and hold it tightly in its place. This result is accomplished by means ofthe inclined side, which causes the plate to wedge into .place when motion is communicated to the car. Y

This reservoir should only be filled with oil below the plate B.

In the center of plate B is a rectangular hole or opening, E, through which the wick or felt passes to the oil.

The upper face of plate B is 4provided. with grooves F leadingfrom the corner. to the opening, and the wick or felt should nearly iill the said hole or opening E. If the box A be used without the plate B, the oil would ne thrown out over the upper edges and a loss would result therefrom; but with this improvement very little, it' any, oil will iind its way above the plate B except what is carried up by capillary attraction through the wick; and any that does escape will tind its way to the grooves F, and be immediately returned back under the plate through the center hole E.

At'one end of box A is a projection, G, that prevents the untimely escape of plate B.

rIllle operation is as follows The box A is filled with oil to the lower surfaceline of the plate B. One `end of a piece of' suitable' wicking or felt is inserted into the oil through the central opening in the plate B, the 4other end boing carl'ied up and turned over the shaft which revolves above. By the revolutionof the shaft the oil is conducted longitndinally in each direction tothe bearings.

Having thus described my invention,

. What I claim, and desire to secure by Letters Batent, is-' 1. The` plate B, lprovided with an opening, F.,and grooves F, substantially as described.

2. The combination of the box A with the plate B,
